BACKGROUND OF THE INVENTION

The present invention is a new and distinct variety of a Rosa L. rose plant obtained from a cross between maternal variety ‘An’ (unpatented) and an unnamed paternal variety of unknown parentage owned by the breeder. The cross was performed by hand pollination in May 2014 and seeds were planted in January 2015. ‘80103WABARA’ was selected from the varieties that flowered in September 2017. Stable characteristics were confirmed following selection. The plant was asexually reproduced by grafting.

BRIEF SUMMARY OF THE INVENTION

‘80103WABARA’ is reproduced by grafting. ‘80103WABARA’ can be distinguished from the maternal variety, ‘An’, by: (1) a large number of petals (128 petals compared to 54 for ‘An’); (2) color grouping (white compared to pink blend for ‘An’); (3) main color of the inner side of the petal (RHS 158D compared to RHS 49C for ‘An’); and (4) petal secondary color (RHS 4D compared to absent for ‘An’). ‘80103WABARA’ is also distinguished from comparison variety ‘Rikuhotaru’ (unpatented) by the main color of the inner side of the petal (RHS 158D compared to RHS 13D for ‘Rikuhotaru’).

The variety ‘80103WABARA’ is maintained at Shiga-ken Moryama-shi, 1465 Sugie-cho 524-0062, Japan and is maintained in soil cultivation. The variety is primarily used as a potted plant and for cut flowers. Planting in Japan is from mid-October to late December. Grafting is from late September to early October. The plant will flower annually when grown in a greenhouse. The plant can be grown at a temperature of 5° C. to 40° C.
